MACHINE FOR OPERATING "UPON'SHOES.

v To alter/tom it mag concern:

Be it known that I, BENJAMIN F. MAYO, a citizen oi the United States,residing at Salem, in the county of Essex and State of lvlassac-husetts,have invented certain improvements in Machines for Operating upon Shoes,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for operating upon shoes, being hereshownin connection with a heel-attaching machine.

Anobject of theinvention is to so organize a work-supporting member, asa j aclnpost, and a worlnpositioning member, as a bandclamp, that thework and positioning members may be brought readily into correctengagement'without danger of defacing the work by the relative movementbetween it and said positioning member. As heelattaching machines arecommonly arranged, as the jack post carrying the shoe to which the heelis to be attached is swung in for the nailing operation, thewband-clamp,which has been raised. by its connection with the jack post to remove itfrom the path of the loader mechanism, descends so that the clamp andshoe converge to the operating position. When they thus meet through asimultaneous ,il'lOVOIl'lGIll), it may not be easy to properly introducethe rear portion of the shoe into theclamp, and the lowerwedge of theband may drag across and rub the upper. In accomplishing thepreviously-mentioned obj set, I provide for control of the movement ofthe worlcpositioning member independently of the work-supporting member.'The positioning member, which as already indicated, may in aheel-attaching machine be the band-clamp, does not, as heretofore, moveonly under the influence of the worksupporting member or jack post, butmay be rem iiorarily secured against movement for later release to moveindependently.

A turther object of the invention is to re duce the breakage of workgages and to render them readily reparable when broken. Inheel-attaching machines, the breast gages, and particularly those whichhold the top lifts, may be subjected to stresses which bend or breakthem. This may arise when the Specification of Letters Patent.

conditions, the gage may be pressed down-- -ward through the yieldpermitted at the clearance between the gage and swing plate and betweenthe swing plate and nail block. There is also sometimes a depressionformed in the swing plate extending beneath the gage, which is employedto produce a convex bottom to the heel. This throws a further strainupon the gage. I arrange the gage to receive such pressure with lessliability to breakage by forming it in sections extending along the edgeof the work, one of which sections is carried by andis yieldable uponthe other. Preferably, the gage sections are connected by a spring,which is shown as located in recesses in the breast-engaging arm of thegage and is secured thereto by rivets.

An additional object of the invention is to provide for maintaining incorrect relation a delivery mechanism and means for actuating an elementthereof. In some shoe machinery. of which the herein illustratedheel-attaching machine furnishes an example,-a movable mechanism and ameans for actuating it are situated upon parts of the machine which maynot be in proper aline- .ment, so that the actuating movement isinterfered with. Considering the specific instance oi'? theheel-attaching machine, a loader arm may be pivoted upon the frame of amachine, while the element which trips the nail gate oi the loader blockis carried by the nail block cross-head. The release of the gate todeliver the nails to the nail block is effected by the contact oi. thegate with its trip when the cross-head is in its normal position, but anadjustment of the stroke of the crosshead, or even an incorrect initialrelation of the parts, may cause the trip to lie outside the plane ofmovement of the gate, so that the tripping of the latter is notaccomplished. In correcting such defects, I have so arranged thedelivery or loader mechanism and the actuating or tripping means thattheir relative positions may be varied to correspond to the variation inthe normal relation of the elements which support them. This adjustment,particularly in connection with loader mechanisms [for heel-attachingEatented Dec. Ltd, 19211.

of the spindle 12 liecting lever 34. 'One arm machines, is preferablyapplied to the tripping means. The time of cooperation of the deliverymechanism and actuating means therefor may also be varied, I-having hereshown the tripping member adjustable in angular position.

The accompanying drawings illustrate a form of my invention embodied ina heelattaching machine.

Figure 1 thereof is a side elevation of a portion of a heel-attachingmachine, illustrating mere particularly the relation between the jackpost and the band-clamp;

Fig. 2 is a top plan View of the heel and top lift holding mechanism andthe loader mechanism, the jack post and band-clamp being removed;

Fig. 3 is a broken detail in rear elevation of the upper portion of thejack post;

Fig. 4 is a perspective view of the crosshead with the swing platemounted thereon;

Fig. 5 shows in perspective a portion of the breast gage; and

Fig. 6 is a vertical sectional detail through the center of the swingpost stud illustrating the manner of holding the nail gate trip thereon.

In the frame 10 are mounted for movement in the usual or any desiredmanner the oppositely arranged work-spindle 12 and cross-head 14. Thecross-head carries the nail block 18, through openings in which act thedrivers 20. At the lower extremity is mounted the jack slide or carrier16, between lugs 22 depending from the under side of which is pivotedupon a pin 23 the jack post, including upper and lower sections 24 and26, respectively. The section 26 is shown as mounted for move mentlongitudinally of the section 24, the sectionsbeing locked in theirnormal position by a latch 30pivoted upon the section 26 and having itstripping portion extending downwardly along the section. At the bottomof the section 26 is the .usual pin 32 arranged to enter the opening ofa last, as illustrated at L, this carrying the shoe S to which a heel isto be attached. The upper extremity of the post section 24 is divided,and between the separated portions, upon the pivot pin 23 as itsfulcrum, is mounted a conof this lever is provided with a hook 36connected, by a chain '38 passing over a sprocket 4O journaled upon theslide 16, to a vertically movableslide 42. This slide 42 is mounted inways in a member 44 upon the frame and carries a band-clamp 46, the band48 of which is arranged to receive the rear portion of the shoe upper,the lower edge of said band entering the rand crease, to hold it inposition for the heel-attaching operation. The other arm of the lever 34contacts with a screw 50 threaded through the front of the post section24. As the jack post is swung outwardly upon its pivot this srrew forcesdown the hook 36 of the lever correspondingly, exerting tension upon thechain 38. Formed upon a segmental portion of the lever 34 is a series ofratchet teeth 52, with which coiiperates a latch device furnished by adetent 54 sliding in a sleeve or casing 56 threaded into one of the lugs22. A spring 58 surrounding a spindle 60 of the detent between its bodyportion and a head of the casing 56 maintains the cooperation of thedetent and ratchet teeth. T0 withdraw the detent from engagement withthe teeth, hand lever 62 is pivoted to. the spindle 60 and fulcrumedupon an extension 64 from the lug below the sleeve 56.

. It extends downwardly along the jack section 24, where it m y bemanipulated conveniently by the operator. There is also shown the usualdetent 66 pivoted upon the section 24 of the jack post and arranged toengage a depression 68 in one of the lugs 22, thus serving totemporarily retain the jack post in its work-receiving position.

For the purpose of describing this feature of the invention, it will beassumed that the heel-attaching operation has just been completed, thejack post, lasted shoe and band-clamp being related as indicated indotted lines in Fig. 1. At this time the chain 38 is slack. As the workspindle rises in the reversal of the measuring movement, the work andband-clamp remaining in the nailing position, the chain becomes taut.The operator then swings out the jack post to the position illustratedin full lines at the right of Fig. l, at the same time removing theheeled shoe. In this movement of the jack post the lever 34 actingthrough the chain raises the bandclamp a. distance equal to themeasuring movement, the ratchet {teeth 52 slipping beneath the detent54, and when the detent 66 engages its depression the band-clamp islocked by the engagement of the detent 54 and teeth. Conse uentlv whenthe 'ack post is returned to the operating position, the band-clamp willbe held at such a height that the lower edge of the band will be at thelevel in whichthe rand crease will move when the jacked shoe is carriedby the jack post into the operating position. When, therefore, theoperator applies another lasted shoe to the pin 32 and forces down thejack post, the shoe enters the band with a substantially rectilinearmove ment while said band is stationary, so that the engagement isperfect and there is no relative movement tending to scratch the work.The operator thereupon depresses the levers 62 and 30. This releases theconnecting lever 34 and the jack post section 26 so that the band-clampand work may be dropped together until the heel seat of the shoe restsupon the heel H carried by the swing plate. When the treadle isdepressedand the jack post eeseends in its measurdng movement, the j ack postsections are restored to their normal relation, latched together by thelever 80' ready for the application ofthe heel to the shoe.

Pivot'ed upon the cross-head 14 above the nail block 18 is a swing plate70, this turning about a stud 72 projecting upwardly from the rear ofthe cross-head. Upon the swing plate are carried holders for heels andtop lifts, these including forks 74 and 76, respectively, adjustableinguides 78, and breast gages 80 and 82, respectively. The

' heel gage may be constructed and arranged in the customarymanner,being drawn toward its fork 1n the gulde 78, as is also the top liftgage, by a spring 84:. The gage .82

has two arms, one of which, designated by i the numeral 86, is guided asis the heel gage,

while the contact arm of the gage is formed in two sections 88 and 90.The section .88 extends for a relatively short distance from the arm 86and is shown as integral there with. It is continued by the alinedsection 90 to the end guide92. The section 90 is connected to thesection 88 for relative movementtoward andfrom the nail block by aspring 9%, here shown as of leaf form and situatedin recesses 96 in thegage sections, the depth of these recesses being such that the top ofthe spring is flush with, or at least not higher than the top of thegage.

The spring may be secured to the sections by pairs of rivets 98, 98. Thecontact arm of the gage is shown as extending over a depression 100 inthe swing plate, though this depression may or may not be used.VVhenpresent, it acts to form a convex surface upon the top lift as itis spanked on the heel.

If, as is sometimes the case,the top lift is thinner than the contactarm of the gage, the overhanging portion of the heel will bear upon it,and by moving it the amount of the clearance spaces between it and theswingplate or between the latter and the nail block or into the swingplate depression may tend to break or deform the contact arm. @naccount, howewr, ot the independence of the sections, the outer one 90,upon which this pressure is brought, may yield sufficiently to usuallyprevent damage, or, if breakage occurs, it will be in the spring 94;.This part is inexpensive and may be readily renewedby cutting off therivets, inserting a fresh spring and riveting it in place. j

. Nails are delivered to the nailblock by a loader mechanism, includingan arm pivoted at 104 upon the frame 10 and carrying a perforatedblock106, beneath which is pivoted the nail-supporting gate 108. A spring110. exerts its tension to swing, the

nailgate frorndbeneath the block, thegate being retained in itsnail-supporting positlon. by a latch pro ectlon 112. The gate isactuated to cause its release from the by adjustment of its actuatingmechanism, T.

adjustably support thel projection on the stud to compensate for this.To this end, the stud 72 has its end projecting through the swing platethreaded at 116, this threaded portion being engaged by a nut 118 havingan upward extension 120 externally threaded. Threaded upon the extension120 is a sleeve 124 vertically adjustable by be ing turned upon theextension. lit is held in the position to which it is moved by a checknut 126 contacting with its upper extremity and also threaded upon theextension. At "its lower end is an annular flange 1255, upon which reststhe hub 130 of the tripping projection 11a. The hub is free to turnabout the sleeve, and near the upper end of the hub said sleeve isthreaded externally at 132 to receive a nut 134:, which when turneddown. against the hub fixes it as to its angular position.

if in the use of the machine it is found that the plane in which thenail gate moves when the loader block is swung over the nail block doesnot bring it into proper engagement with the trip 114i, the location ofthis tripping projection may be varied vertically by the organizationjust described. This is accomplished by releasing the nut 126 andturning the sleeve 124 up or down until the projection 11 i is found tobe correctly engaged by the latch 112. The nut 13 1- being freed fromits contact with the hub 130, the projection may be turned upon theflange 128 until the time at which the gate is tripped is such that thenails are properly delivered to the holes in the nail block.

The machine in its general operation may differ in no essential respectfrom the usual heel-attaching machines of this type and this will notparticularly be described.
